You'll want to take that out and clean it up when you can, then add some star san back in it. If it gets too full, the beer can fall back into the bucket and you may risk an infection. Not something you want on your first batch.

It sounds like the instructions said to do a 90 minute boil? It is done with lagers & the like with mash out temps,etc. But with steeping? Normally,you steep the grains,maybe sparge (rinse) them to get your boil volume. Then add about 2 pounds of the extract to the boil,adding LME off the heat so it doesn't scortch when it goes straight to the bottom. Then bring to a boil,watching for the foamy hot break right before it boils,if any. When it boils,add the bittering hop addition. Flavor additions are usually 25-10 minutes left in the boil. 3-5 minutes left for aroma additions. That's atypical anyway of most kits here.
And def rig a blow off tube next time. But do keep the airlock cleaned out & sanitized. I picked up a few extra airlocks for my 2 fermenters,so I can change them out quicker. I use cheap grocery store vodka in my airlocks,since Starsan foams up & out with all the bubbling. Vodka dosen't,& anything that settles into it dies of alcohol poisoning.

I have b-brite...I can pull the airlock and re-san it quickly during lunch if you all think that's necessary. The liquid is well below the level of the tube though...I don't see any way that anything is going to fall back into the beer tbh

The problem comes in when initial fermentation slows to a crawl to finish fermenting down to FG. At that point,the temp starts going down,& a partial vacuum is created. This causes a suck back through the airlock,& all that nastie stuff gets sucked into the fermenter. That's why it needs to be kept clean,& why I use cheap vodka in mine.

I really like the idea of cheap vodka...I didn't understand what you meant at first by that. I'll pick some up at lunch today and sanitize my airlock and put it back on with that in there. Its going like gangbusters right now so I'm not worried for the time being. Stupid question...could I just sanitize the airlock with the vodka rather than the sanitizer? Seems like that would have the same effect

I spray the stalk of the cleaned airlock with Starsan I keep in a spray bottle,So when the stalk goes into the grommet in the FV lid,it won't bugger anything. Then fill to the line with the cheap vodka. Works fine for me. For a while,I bought the cheap vodka in those 1/2 gallon plastic jugs. They make great blow off jugs 1/3 full of water with a splash of Starsan.

I'm in the same boat - primary'd & pitched last Tuesday, fermentation lasted til Friday, and now I'm in the business of keeping the primary under 75F during this hot summer weather. Batch #2 gonna get cooked up soon.

As Tom Petty once said, waiting is the hardest part, but it won't be so difficult once I've already got some home brew to drink. It's this first batch that's making me impatient.

Well, the dry hops are in now and since I had it cracked open (what a great aroma wafted out 8) ) I spooned some into a glass for a little taste. I'm very happy with how this coming out! It was pretty decent warm and not completely finished. Will it stay as cloudy as it was?
